A new approach is proposed for constructing regular low-density parity-check (LDPC) codes based on tensor product of matrices. In this paper, first a general construction method of regular LDPC codes… (More)

We describe a symbol detection scheme for multilevel two dimensional optical storage (TwoDOS), where the channel is characterized by non-linear inter symbol interference and the dominant source of… (More)

We consider a practical system design for a wireless video conference application, where we exploit the broadcast nature of wireless radio links using network coding. With network coding, the number… (More)

Recently, a symbol detection scheme based on the Viterbi algorithm was proposed for binary Two Dimensional Optical Storage (TwoDOS) in the presence of Additive White Gaussian noise (AWGN). In this… (More)

A new and challenging concept for optical storage is being developed, in which the information written on the disc has a two-dimensional characteristic, with the aim of realizing an increase of a… (More)

Near-optimum sequence detection in channels with intersymbol interference (ISI) is based on the Viterbi algorithm. However, its complexity increases exponentially with the number of taps within the… (More)
